92red5.0

hi everyone just looking for some help. i recently bought a 1995 f150 with a 5.8 with an e4od. i am having trouble with how it runs. when i first start it starts great but after it warms up its hard to start it cranks alot and smells like raw gas i have to put my foot on the gas a tiny bit sometimes to start it. i pulled the trouble codes and i got 2 back code 624 and code 172. i do have a chiltons book. i have changed the tps, map, egr valve, and the iac. i do have a small manifold leak too. any help would be great thanks. i can give more info if needed

I just went through the 172 code, it was intermittent and even passed smog, after looking at the O2 sensor close I found the wires were brittle and cracked, new 50 dollar part and truck runs smooth, no idea on the 624
